Mommy Hippo: Well their is carbon dioxide and sodium chloride, but there are many more.
Baby Hippo: Wait! What are elements then.
Mommy: Elements are pure substances that can not be broken down into simpler substances.
Baby: Oh, okay. Mommy I have a test for you. Remember that red stuff that pours out of our food and then mixes with the water to look different? What is that
Mommy: Haha that is a mixture or combination of two or more substances that aren't chemically bonded. Now I have a test for you. What is a compound?
Baby: I'm pretty sure it's a pure substance composed of two or more elemetns that are chemically combined.
Mommy: Good job, I love you.
Solution:
A solution is a mixture of one substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent.
The solute is the substance being dissolved and the solvent is the part of the solution that does the dissolving. The solute is of molecular size. http://www.edinformatics.com/math_science/solutions.htm
